Problems With Having Two Capital Cities
Some Germans today question the inefficiencies of having more than one capital city. The cost to fly people and documents between Bonn and Berlin on an ongoing basis costs millions of euros each year.
Germany's government could become much more efficient if time and money were not wasted on transportation time, transportation costs, and redundancies due to retaining Bonn as the second capital.
At least for the foreseeable future, Germany will retain Berlin as its capital and Bonn as a mini-capital city.
